Abstract
Embodiments for a cryohead heat transfer coupling as well as methods for extracting heat from an article using these couplings are provided. Couplings employ a component made from a material having a greater mean thermal coefficient of expansion than the mean thermal coefficient of other coupling components and of the article. As a result, differential contraction during cryocooling contributes a shrink fitting of a portion of the coupling resulting in enhanced thermal conduction when cooling and a releasing of the coupling when ambient temperature is restored.
